توضیحاتی در مورد کتاب نحوه کار لینوکس: آنچه هر کاربر فوق العاده باید بداند

چگونه لینوکس کار می کند داخل سیستم لینوکس را برای مدیران سیستم ها توصیف می کند، خواه یک شبکه گسترده در دفتر داشته باشید یا یک جعبه لینوکس در خانه. برخی از کتاب‌ها سعی می‌کنند دستورالعمل‌های کپی و جای‌گذاری را برای نحوه برخورد با هر مشکل سیستمی که ممکن است پیش بیاید به شما ارائه دهند، اما چگونه لینوکس کار می‌کند در واقع به شما نشان می‌دهد که سیستم لینوکس چگونه کار می‌کند تا بتوانید به آن برسید. با راه حل های خودتون نویسنده برایان وارد پس از یک گشت و گذار در سیستم های فایل، دنباله راه اندازی، اصول مدیریت سیستم و شبکه، به موضوعاتی با پایان باز مانند ابزارهای توسعه، هسته های سفارشی و خرید سخت افزار می پردازد، همه از دیدگاه مدیر. این کتاب با ترکیبی از تئوری پس‌زمینه و مثال‌های دنیای واقعی، هم \"چگونه\" را برای مدیریت لینوکس و هم \"چرا\" را نشان می‌دهد که هر تکنیک خاصی کار می‌کند، بنابراین شما می‌دانید که چگونه لینوکس را برای شما کار کند.


توضیحاتی درمورد کتاب به خارجی

How Linux Works describes the inside of the Linux system for systems administrators, whether you maintain an extensive network in the office or one Linux box at home. Some books try to give you copy-and-paste instructions for how to deal with every single system issue that may arise, but How Linux Works actually shows you how the Linux system functions so that you can come up with your own solutions. After a guided tour of filesystems, the boot sequence, system management basics, and networking, author Brian Ward delves into open-ended topics such as development tools, custom kernels, and buying hardware, all from an administrator's point of view. With a mixture of background theory and real-world examples, this book shows both "how" to administer Linux, and "why" each particular technique works, so that you will know how to make Linux work for you.
